Keyhole Saw Types
– Fixed blade type: commonly used in modern construction trade
– Retractable blade type: has a cast-iron or wooden handle
– Retractable feature prevents blade flex when obstructed
– Blade secured by holding/thumb screws
– Cheaper and more widely used in construction trade
Uses of Keyhole Saw
– Cutting small and awkward features in building materials
– Specifically designed for certain building methods and materials
– Can push or jab through soft materials like drywall without drilling
– Compass saws used for tougher materials
– Jigsaw and spiral saw are power tools with similar functions
Keyhole Saw Modifications
– Sharpened point at the tip of the blade for easier penetration
– Allows cutting through soft materials without drilling a hole
– Developed for specific trades in the construction industry
– Designs catered to advancements in building methods and materials
– Cost-effective option for various construction tasks

A keyhole saw (also called a pad saw, alligator saw, jab saw or drywall saw) is a long, narrow saw used for cutting small, often awkward features in various building materials. There are typically two varieties of keyhole saw: the fixed blade type and the retractable blade type.

The retractable-blade variety is usually found to have either a cast-iron handle or, less commonly, a wooden handle. The facility to retract the blade to an optimum length serves to prevent unwanted flex to the blade should the full length of the blade be obstructed in some way. In both types, the blade is typically secured by one or two holding/thumb screws.
The cheaper, fixed-blade type is more commonly used in the modern construction trade. With the advance of certain building methods and materials, designs specific to these trades have been developed. One such modification being a sharpened point at the tip of the blade which can be pushed or jabbed through soft materials such as drywall without drilling a hole for the blade.
Compass saws typically feature a larger, coarser blade, and are designed to cut through tougher materials.
Two power tools serving largely the same function but which work more quickly and with less effort are the jigsaw and spiral saw.
